ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 328,070, dated October13, 1885.

Application filed September l, 1885. Serial No. 175,896.

.To a/ZZ whom t may concern:

Be it known that I, J AcoB VoEE RowLE'rT, a citizen of the UnitedStates, residing at Richmond, in the county of Wayne and State ofIndiana, have invented new and useful Improvements in Roller-Skates, ofwhich the following is a specification.

My invention relates to roller and other skates in which the foot-plateis secured to the foot of the wearer by clamps,or by clamps and strapscombined.

p It is the purpose of my invention to simplify and improve theconstruction of the clampguides which carry the arms upon which theclamping -jaws are mounted, whereby the strength and durability of theparts are greatly promoted and the clamps rendered more efcient inoperation, while the time, labor, and expense of manufacture are at thesame time materially diminished.

To these ends the invention consists in the several novel features ofconstruction and combinations of parts hereinafterfully set forth,anddefinitely pointed out in the claims annexed to this specification, thesame being an improvement upon the invention shown and described in anapplication for Letters Patent led by me upon the 23d day of June, 1885,numbered in serial 169,593, whereof the present application is adivision.

Referring to the drawings forming part of this application, Figure l isan inverted plan view of a skate embodying myinvention. Fig. 2 is aperspective view of the bracket and clamp-guides removed from thefoot-plate. Fig. 3 is a detail section taken in the plane x x, Fig. 1.Fig. et is a detail view showing a modied construction.

In the said drawings, the reference-letter A designates the foot-plate,having brackets B and C at the toe and heel, respectively. Thesebrackets and the parts connected with them are, save in the particularshereinafter specified, of the ordinary construction.

Upon the bracket B, which lies near the toe of the foot-plate, areformed laterally-projecting plates D, having their forward edges insubstantially the same straight line. These edges may be coincident, ornearly so, with the end of the bracket, or they may lie in front or inrear of the same to a limited degree; but

(No model.)

I prefer the construction first mentioned. The plates D are cast orotherwise formed upon the bracket in such a manner that when the latteris applied to the foot-plate said plates will lie fiat upon the undersurface of the same. Their forward edges are beveled, as shown, and formpart of the guides for the clamps upon the toe of the foot-plate. y

The letter E designates a plate which is coextensive, or nearly so, withthe width of the foot-plate. Upon the central portion of this plate iscast or otherwise formed ayoke-piece, F, having an extended toe orpoint, f, thesaid yoke-piece being provided with a bifurcation, f', fora purpose presently to be shown. The edge of the plate from which theyoke-piece projects is given a bevel opposite to that of the plates D,and ears e are formed upon or near the ends of the plate, whereby it maybe fastened to the foot-plate.

Vhen the parts are in position, the projecting end or toe flies in arecess, b, formed in the end of the bracket,and open upon the side nextto the foot-plate. Both the bracket B and the plates D are fastened tothe foot-plate by rivets d, passing through the plates, and through lugsb', formed upon the rear end of the bracket. rlhe plate E is thenapplied, the toe of the yoke-piece F being inserted and snugly fitted iuthe recess in the bracket, and rivets e are passed through apertures inthe ears e and in the foot-plate. rlhe parts described are thus adaptedto serve as guides for the clamps G, while the reversely-threaded shaftI is seated in the bifurcation f of the yoke-piece.

The construction described may be slightly modified to adapt the partsto be used in connection with the rear or heel bracket. In this case theplates D (shown in Fig. 4) are cast or otherwise formed upon the sidesof the bracket C in' the manner described. The parallel guides are thenformed by means of plates E', extending laterally from a raised centralportion or bridge-piece, F, which straddles the truss-brace L andcarries a boss, F2, which is tapped to receive the tension-screw M.Projecting centrally from the inner edge of the bridge-piece F is a toe,f2, which has formed upon its outer surface aseat for theclamp-actuating screw, I, the extended point of said ICO toe beingreceived in a recess between the bracket and the foot-plate in themanner alreagy described in connection with the bracket By thisinvention I greatly increase the strength and durability of theclamp-guides and materially reduce the cost and labor of produ cing thefinished skate. Under the usual construction, the clamp-guides havingbeen separate from the bracket, at least two additional rivets wererequired for the attachment of the bracket to the foot-plate. Thisnecessitated drilling at least four extra holes in the foot-plates ofeach pair, and as many more in the guide-plates. rIhis, together withthe insertion and upsetting of the rivets, is an important item in alarge factory. Moreover, by my invention increased strength andfirinness are imparted tothe clamp-guides, since by connecting the outeror separate guide-plate With the bracket in the mannerY described asgreat strength and power of resistance are iinparted to the structure asif the whole were east in one single piece.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

1. In a roller or other skate, abracket having clamp-guides east orotherwise formed thereupon, in combination with a parallel plate cast orformed separately, and havinga proj ectin g portion, which lies in arecess formed in the end of the bracket, substantially as specified.

2. In a roller or other skate, the combination, with a bracket havingclamp-guides cast or otherwise formed integral therewith, of a parallelguide having a central projecting portion which underlies the end of thebracket and forms aseat for the clamp-actuating screw, substantially asspecified.

3. In a roller or other skate, a bracket having clamp-guides cast withand projecting laterally therefrom, a separately-formed guideplatehaving a central integral projection underlying the end of the bracket,and a clampaetuating screw seated in said projecting portion,substantially as specified.

4. In a roller or other skate, the combination, with a bracket having arecess in its end and provided with clamp-guides castor formedintegrally therewith, oi' a separately-formed parallel plate having acentral bridge-piece, and having its end lying in the recess in thebracket, a clamp-actuating screw seated inthe bridge-piece, and atension-screw tapped into a boss carried by the latter, substantially asspecified.

In testimony whereof I aflix my signature in presence of two witnesses.
